4.4 AIX-specific startup and runtime settings

To check for AIX-specific conditions during boot, refer to the bootlog files located in directory /var/adm/ras/. For this reason, we changed the size of the bootlog files from 4096 bytes to 64000 bytes. We also changed the verbosity to 3 by using the alog command as shown:

alog -C -t boot -f /var/adm/ras/bootlog -s 64000 -w 3

alog -C -t boot -f /var/adm/ras/conslog -s 64000 -w 3

To allow users to fork additional processes (and because this AIX setting affects DB2 performance), we increased the maximum number of processes per user. We used the chdev command to set the maxuprov value to 200.

chdev -l sys0 -a maxuproc='200'
